.To a/ZZ whom it may concern:

Beit known that We, FREDERICK G. HUGHES and ROBERT P. STOUT, citizens ofthe United States, residing at Bethlehem, in the county of Northamptonand State of Pennsylvania, have invented certain new and usefullmrovements in Wheel-Bearings, of which the ollowing is a speciiication.

Our invention relates to the journals and o hubs of Wheels primarilyintended for use in connection with the Wheels of vehicles, but adaptedto be employed Wherever a Wheel r0- tates upon a spindle withintervening hiotion-bearings; and our invention conslsts in providingthe journal With cylindrical bearing portions for antitriction-rolls andthe hub with detachable annular bearings or sleeves for said rolls andconstructingv the parts as fully set forth hereinafter, so as tofacilitate zo access to the parts, permit the ready removal of the rollsand detachable bearings, and eX- clude dust, all as set forthhereinafter and as illustrated in the accompanying drawing, in which thefigure is a longitudinal section z 5 ci a journal, part of an axle, andWheel-hub lembodyin our improvements.

The a" e D terminates in a journal T, which may be secured to or formpart of the arde and which has a flange 19 at the rear, a

jo cylindrical bearing portion 21 adjacent to 'the ange, a'nd a terminalcylindrical bearing portion 20, said bearing portion being adapted toantiriction-rolls S S, carried by the hub of the Wheel W. l/Vithin saidhub are two an- 3 5 nular bearings or sleeves Q R, oi hardened andground steel, which inclose the antiiriction-rollers S S and which aresecured immovably in the hub in any suitable manner. As shown, one endof each sleeve Q has an an- 4o nular flange 23 With an annular groove24, adaptedto receive studs 25, projecting from the rollers at one end.

' The studs at the outer end of the rollers S, Within the sleeve Ov,extend into an annular 4 5 groove 25m a cap l?, having a threaded flangeadapted to the end ci the inner tubular section N 'of the hub, the endof the flange of the cap P bearing against the edge of the other sectionO of the hub, which section incloses 5o the outer end or" the innersection, and each section of the hub is provided with an annular Bangee, the on tts or the spokes ltting belface of the sleeve,

tween the two flanges 4 4 and being secured by bolts Y, passing throughthe flanges and through grooves formed in the adjacent spokes.

An annular. retaining-rin V is secured to the inner hub-section N an hasan annular recess 28 to receive the studs 25 at the inner ends of therollers S Within the sleeve R, the 6o ring V being secured to thehub-section N by taper-pins 29, passing transversely through openingsformed partly Within the ring V and partly in the hub.

Between the centrallportion of the journal l and the hub-section is anoil-chamber 7,` which, as shown, is formed partly in a recess of thejournal and artly in the corresponding recess oi the hu and upon thelatter is a series of longitudinal iianges or ribs 31, which 7c -agitateand disperse the oil admitted to the Y chamber through an opening 32,provided with a self-closing valve 33. By this agitation the lubricantis thoroughly distributed and carried toward both the bearings and toboth series of antifriction-rollers.

It Will be seen that the inner edge of the hub fits closely against the.flange 1.9 of the journal, While the cap P completely seals the journaland bearings at the outer end, so that 8o there is no possibility oftheaccess of dust to the parts. The hub is held against the flange 19, butso as to turn freely'upon the journal, by means of a clamping-ring M, orin any other suitable manner. 85

It will be seen that the cap P may be readily removed, as by a Spannerengaging lugs 8 on the cap, and that this permits ready access to removethe outer rolls S or the sleeve Q, which is prevented from turning by ascreW- 9o stud 84, the end of Which engages thel flat and that bydriving out the pins 29 the ring V may be removed, permitting accesstothe inner series of rolls S and also the removal of the sleeve R,which is revented from turning by a screw-stud 35.v

t will be seen that the sleeves Q R are detachable longitudinally on theremoval of the cap P and ring V and that as the rollers are retained inconnection with thehub b their roo studs fitting the annular grooves oft e cap and rin and sleeves the wheelmay be removed lrom the axleWithout separating the rollers from their sleeves.

Y Without limiting ourselves to the precise construction and arrangementof parts shown, we olaim-- 1. The combination of a journal having 'abearing portion, a hlb, an internal removable sleeve therein, haw'ng anend fia-n e with an annular groove therein, a detaeha le ea having anannular groove, antifriotion-rol s between said bearing portion andsleeve and .extending at their ends into said grooves, and means toprevent the sleeve from turning While permitting its longitudinalWithdrawal, substantially as set forth. A

2. The combination of the hub having a fixed ange and movable flange, ajournal x 5 In testimony whereof We have Signed our zo y names totlfiisspecification in tlie presence of two subsqribmg Witnesses. f f
